Can someone please help me figure out which terms match these definitions for nuclear physics? 1. Process in which a nuclide is transformed into a nuclide of a different element. 2. Total number of nucleons remains constant. 3. A radioactive transformation of a nuclide in which a bound electron merges with its nucleus. 4. A particular type of radiation emitted by a radioactive substance. 5. A radionuclide that upon disintegration yields a specific nuclide. 6. The division of an atomic nucleus into parts of comparable mass. 7. The mass of fissionable material of a particular shape that is just sufficient to sustain a nuclear chain reaction. Thanks! Also I was wondering if an alpha particle has enough kinetic energy can it penetrate the nucleus of an atom and establish strong nuclear force?
